Why do I get an error when I put a call for the output of a function (defined within a function) *after* the...
My code does what I want it to do, but I want to understand why it does what it does. I find that in MATLAB if I call for the output of a function after the definition of the function, I get an error, but not if I call it before the function's definition. My impression is that MATLAB is putting the cart before the horse, and I'd like to know why I am mistaken in that impression.
function [out,outt]=f_testFunctionWithinFunction(arg_in)
% function has to be invoked BEFORE its definition.
out=f_inside(arg_in);
function use=f_inside(argg_in),
use=sin(argg_in);
return
outt=f_inside(arg_in);
return
The expression out=f_testFunctionWithinFunction(5)
yields -0.9589=sin(5)
. However, [out,outt]=f_testFunctionWithinFunction(5)
yields an error message, due to asking for "outt"
. Why?
matlab function nested

If you want to know how to define functions you can read about function. Alsolocal functions
should be distinguished fromnested functions

you should end functions with end
, instead of return
. try:
function [out,outt]=f_testFunctionWithinFunction(arg_in)
% function has to be invoked BEFORE its definition.
disp('test')
out=f_inside(arg_in);
function use=f_inside(argg_in),
use=sin(argg_in);
end
outt=f_inside(arg_in);
